website for architecture and civil eng. Service

I'm looking for a website to advertise my architecture and civil engineering services. I offer Construction Management and plan to have an e-commerce function to sell my services directly through the website. My estimated budget for the project is less than ₹20000. It's important that the website is easy to navigate, modern, and contains accurate information. I am seeking a developer who can provide a professional, high-quality website within my budget that meets my needs.
